Any recommendations for a good scary book?

[zestyflavour]

I've looked at previous threads and have read The Ritual, Reiko, Birdbox, but now looking a good scary book. What's the best scary book you've read? Recommendations please

Haunted by James Herbert. The Shining and Pet Sematary both by Stephen King

[Flamingoringo]

Dark matter by Michelle paver

[snozzlemaid]

Mo Hayder's Birdman and The Treatment are good.

[WillWorkForShoes]

The Waiting Room by Francis Cottom. Proper freaked me out!

Mo Hayder - Pig Island. I lent it to a friend and I'm not allowed to lend him her books anymore.
